Thanks for detailing your SD3 problems Jim - sorry to hear how unhelpful Ketron have been.
I fully agree with you that everything should work normally even if some features are not used on a regular basis.

I have been a big Solton / Ketron fan for many years and am amazed and extremely disappointed at their treatment of so many loyal customers.
Leaves us in a position where we hardly dare contemplate another purchase from them under these circumstances - what a way to run a business. Can't see them lasting much longer at this rate.
